1 Claim. (Cl. 306-1) This invention relates to a magnetic handleconnection.

It is an object of the present invention to provide a household cleaningdevice wherein the same handle can be used for the different attachmentsand wherein the attachments are held and fixed to the handle by magneticattraction between magnet or magnetizable parts employed upon the handleand the attachment.

It is another object of the present invention to provide a householddevice including a handle and attachments therefor wherein theconnection of the attachment to the handle can be effected in anexpeditious manner and without the need for a turning action to effectthe coupling of the parts, but wherein the coupling action is effectedby merely locating the attachment in the handle so that magnetic actiontakes over and couples the attachment to the handle in a tight mannerand wherein the handle may be so formed with a sleeve as to enclose themagnetic or magnetizable pieces to provide for all appearances astandard household device with inseparable parts.

Other objects of the present invention are to provide a household devicecomprising a handle and attachments therefor which are coupled with thehandle by magnetic means, which is of simple construction, inexpensiveto manufacture, has a minimum number of parts, compact, requires littlespace for the storage of the attachments and handle, convenient to use,and efficient in operation.

The advantages of this invention lie in the fact that the one stick orhandle piece saves closet space and storing time and wherein a standardpeg for the respective attachments will all fit the handle and themagnet having a standard opening therein. The magnetic principle makeseasy the attaching and detaching of the attachments. With the handlebeing formed of plastic or aluminum tubing, it will be light in weightand less eort will be required to use the device. With the magnet beingof stainless material and the handle and other parts being formed ofaluminum, the device will not rust and will have long life. By the useof a pivoted magnetic pin on the combined brush and buffer attachment,the attachment can be easily and quickly inverted to use either thebrush or the buffer.

For a better understanding of the invention, reference f may be had tothe following detailed description taken in connection with theaccompanying drawing, in which Fig. 1 is a collective and perspectiveview of the device embodying the features of the present invention andshowing a broom attachment separated from the handle.

Fig. 2 is an enlarged sectional View taken generally on line 2-2 of Fig.l, but with the attachment coupled to the handle.

Fig. 3 is a perspective view of a squeegee attachment adapted for usewith the handle shown in Fig. l.

Fig. 4 is a collective and perspective View of a handle and a mopattachment separated from one another.

Fig. 5 is a perspective view of a device for hanging the attachmentsupon a wall.

Fig. 6 is a vertical sectional view taken through a modified form of theinvention.

Fig. 7 is a vertical sectional view of a still further modified form ofthe invention.

Fig. 8 is a perspective view of a combined brush and buffer elementwhich may be attached to the handle.

Referring now particularly to Figs. l to 5, 10 represents a handle whichmay be preferably made from aluminum or plastic material and which islight in weight. The lower end of the handle is open and fittedthereinto is a magnet 11. This magnet is made secure by crimping2,697,642 Patented Dec. 21, 1954 the handle material into an annularrecess on the magnet and in the manner as indicated at 12. This magnet11 has a tapered opening or frusto-conical recess 13 into which may beprojected a magnet or magnetizable piece 14 of either a broom 15, asqueegee 16 or a mop 17. The piece 14 is tapered or frusto-conical tofit the tapered opening 13 whereby to provide a tight but releasable fitand whereby to provide for the maximum effect of the magnetic actionbetween the magnet 11 and the piece 14. The piece 14 has a threadedshank, as indicated at 18 for effecting its connection with theparticular attachment. The handle sleeve is preferably made to projectbelow the end face of the magnet 11 in order to receive the upperportion of the broom attachment to have a smooth connection therewithand its end face to rest upon a shoulder 19 thereof.

In the case of the squeegee 16, the piece 14 can be threaded directlyinto the squeegee which is formed of brass or other non-magnetizablematerial. The squeegee element or wiping portion 21 is secured to thesqueegee body in the usual manner by means of pins 22.

The mop 17 has a magnet or magnetizable piece 23 which is pivoted bymeans of a pin 24 to a frame 25 of the mop. Depending from the frame 25are the usual threads 26. The piece 23 has a tapered projection 27adapted to enter the opening in the magnetic or magnetizable piece 11 ofthe handle 10.

In Fig. 6, there is shown a modified form of the invention wherein themagnetic means on the handle part includes a magnetic or magnetizablesleeve 28 which is secured to a wood handle portion 29 by a pin 31.Within this magnetic sleeve 28 is a magnet 32 having a tapered end 33.This magnet can be fixed to the end of the wood handle portion 29 by afastening projection 34.

The broom part 15 has a magnetic or magnetizable piece 35 connected toits upper end by a threaded shank 36. This magnetic piece 3S issimilarly tapered and has an end portion 37 adapted to engage the endportion 33 of the magnetic piece 32. The magnetic piece 32 will havemagnetic attachment with the magnetic sleeve 28 so as to bridge amagnetic path to the side wall of the magnetic piece 35. Accordingly, atriple magnetic engagement is effected with this arrangement of themagnetic pieces 32 and 35 within the magnetic sleeve 28. The magneticsleeve 28 extends sufficiently below the magnetic piece 32 as to fullyencompass the magnetic piece 35 and the upper portion of the broom 1S.

In Fig. 7, there is shown a still further form of the invention, whereinthe handle part 41 which is of hollow formation, made of aluminum orplastic and having a cylindrical-shaped magnet 42 fixed therein V/bymeans of a pin 43 extending transversely through the handle and themagnet. The magnet 42 is spaced a substantial distance from the openbottom end of the handle 41 and is adapted to receive a magnetic ormagnetizable piece 44 which has threaded engagement with a brushattachment 45. Since the handle part is of non-magnetic material, thecoupling action is effected magnetically primarily through the upperface of the magnetic or magnetizable piece 44 and the lower face of themagnetic or magnetizable piece 42. If both pieces are magnetic,

an added effect is had. Since the magnetic piece 44' enters the handlepart 41, it is further mechanically held against lateral displacementrelative to the lower end of the handle part 41 by its uniontherewithin.

To de-couple or separate the attachment from the handle part in each ofthe forms of the invention above related, the foot may be placed uponthe attachment and a pull effected with the handle. The magneticattractive force which, while it is great between the magnetic ormagnetizable pieces, is not sufficient to withstand the sudden pull uponthe handle while the attachment is being retained in a fixed position.

With the attachments removed from the handle part, they can be storedeasily upon a holder 47, Fig. 5, having a magnetic piece 48 disposedacross its lower end. The attachments will be abutted upon the magneticpiece 48 with its magnetic piece and will remain suspended from theholder until pulled therefrom.

The squeegee 16 can be provided with a magnetizable piece 16' on one endwhich can be attached to the magnet 48 so that the squeegee can besuspended in a manner so as not to consume great space and angled fromthe position shown in Fig. 5. This magnetizable piece 16 is indicatedclearly in Figs. 3 and 5. There is also provided upon the pegs 14 holes14 by which the attachments can be suspended from nails on a wall.

In Fig. 8, there is shown the combined brush and buffer attachment. Thisattachment has a main ,plate 51 with a slot 52 in one edge of the sameand across which extends a pin 54 on which magnetizable peg 55 ispivoted. The plate 51 has brush bristles 56 depending from the same anda buffer cloth 57 on the top thereof. Inasmuch as the peg S5 can beadjusted through the opening 52, the combined brush and buffer can beeasily and quickly inverted to apply either the brush or the buffer.

Not only can the buffer and waxer attachment be applied, but a goodmany'other types of attachments, such as a liioor scrubber, a sponge, aparlor broom, a carpet sweeper, ksilent butler or window washer. Theinvention eliminates the need for screws or other elements which wouldbe necessary for the effecting of a handle within an attachment notutilizing my magnetic lifting principle.

While several different types of attachments have been shown, it will beapparent that any further types of attachments can be used with thishandle. A long feathertype brush, as indicated at 49, might be used.

It should be apparent that there has been provided a household devicewherein the attachment can be connected to the handle part with littleeort and similarly disconnected. The device is of simple constructionand has a minimum number of parts and will have the same stiffness as anordinary device without the separable feature and can be worked and usedin the same manner.

It should be further apparent that the attachments being separable fromthe handle can be more readily stored `and will consume little space inthe storage closet.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

What is claimed is:

A household device comprising a handle formed of non-magnetic materialand having an open sleeve portion at one end thereof with an end facethereon, a magnet secured within the sleeve portion spaced inwardly ofthe end face thereof, said magnet having a frusto-conical recessaccessible through the end face of the sleeve portion, a releasable workelement formed of nou-magnetic material, said work element having aprojection extended into the sleeve portion of the handle and a shoulderengaged by the end face of the sleeve portion, and a frusto-conicalmember of magnetizable material having a shank secured in the Workelement projection and conforming to and releasably fitted in thefrusto-conical recess of the handle magnet, whereby to magneticallyretain the work element in the handle against axial displacementtherefrom.
